AK7722
DESCRIPTION
The AK7722 is a digital signal processor with an integrated 4ch 24bit DAC, a stereo ADC with input selector and a 2ch input ADC. The integrated 4ch DAC, the 2ch ADC with input selector and the other 2ch ADC feature high performance achieving 108d B, 96d B and 95d B, respectively. The integrated SRC has three input selector enabling the DSP to operate in master mode with digital inputs. The audio DSP has 1536step/fs (at 48k Hz sampling) parallel arithmetic operation performance and the 5k-word delay RAM allows surround processing and time alignment adjusting. As the AK7722 is a RAM based DSP, it is programmable for various user requirements. It is housed in an 80pin LQFP package.
